OATEY 273888 – Frequently Asked Questions
1) What pressure range does the Cherne Econ-O-Pump test pump read?
The Cherne Econ-O-Pump comes with a 200 psi gauge, protected by a cover so the face survives being tossed in a truck bin. That range covers typical DWV air testing and hydrostatic plumbing tests where readings sit well under the gauge's top end.
2) Does the Cherne test pump include the test plug or ball I need to pressurize the line?
No. The 273888 Econ-O-Pump is the pump and 200 psi gauge only. The inflatable test ball or mechanical test plug for the pipe size you are testing is a separate purchase, and so is any extension hose you want between the pump and the plug.
3) Is the Cherne Econ-O-Pump a hand pump or does it need power?
It is a manual hand pump. There is no motor or power connection on the Econ-O-Pump, which is why the whole unit weighs about 4.05 lb and travels as a one-hand tool to the test riser.
4) How does the Econ-O-Pump hold pressure while you take a reading?
It uses a traditional thumb lock. You pump up to pressure and the thumb lock holds the stroke so the gauge stays loaded while you watch for a drop, instead of having to keep hand pressure on the handle.
5) What is the exact part number to order the Cherne Econ-O-Pump?
Order Oatey part number 273888. That is the Cherne Econ-O-Pump test pump with the 200 psi covered gauge and thumb lock, in black, and it is a single configuration with no size or option choices to specify.
6) Is the Econ-O-Pump light enough to carry up a ladder or into a crawl space for DWV testing?
Yes. At roughly 4.05 lb and about 0.4 cubic feet of volume, it is a tool you can carry in one hand along with your test ball, which is the normal way plumbers use it for inflating test balls on rough-in DWV inspections.
